I have a transmitter circuit that has 75ohm impedance with the F-type connector. I need to connect this device to a 50ohm impedance power splitter/combiner with SMA type connector. The transmitter device is operated at UHF frequencies around 470-600Mhz (nothing over the air, all testing is done via cables). Is there a DIY solution to build a impedance matching circuit which can work in the above mentioned scenario ?
Edit : The transmitter's output power is around 26dBm to 30dBm, which is very low power.
